PNGQR (Ping-queer?)
-------------------
Pure Ruby Gem to generate PNG files of QR codes.
Usage
-----
Example:
require 'pngqr'
Pngqr.encode 'https://github.com/andys', :file => 'output.png'
The parameters for encode() are the same as the rqrcode gem's new(), except:
1. we add :file if you want to output to a file instead of returning the PNG as
a blob, and
2. you can :scale with an integer parameter and it will scale up the output
image by that many times.
3. if you don't supply a :size, we auto-size by testing each size until we
find the one that worked. It seems quick enough.
4. :border=>n lets you add an n pixel white border to the PNG
Dependencies
------------
Gems: rqrcode and chunky_png (both pure ruby gems)
